What is B002A?

The DTC code B002A indicates an issue with the airbag crash sensor circuit, particularly in vehicles like the 2015-2020 Ford F-150 and Chrysler 300. This fault typically points to a malfunction in the crash sensor or its wiring, which can prevent the airbag system from activating in the event of a collision. When this code is triggered, the airbag warning light on the dashboard will illuminate, indicating a serious safety concern. Drivers may experience a loss of airbag functionality, meaning that in the unfortunate event of an accident, the airbags may not deploy as intended, increasing the risk of injury. Treating this code requires immediate attention; ignoring it can lead to serious consequences during a crash. Additionally, it's important to consider that other faults in related systems, such as the seatbelt pretensioners or the overall airbag controller, may also be indicated by this code. Vehicle owners should not attempt to drive their vehicle without resolving this issue, as airbag systems are integral to passenger safety.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B002A is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a malfunction in the airbag system.
  • Drivers may notice that the vehicle feels different in a crash simulation, as the airbag may not deploy properly.
  • There can be a noticeable delay in the vehicle's response during airbag diagnostics, with potential failure to complete the airbag system self-test.
  • In some cases, you might hear a clicking sound from the airbag unit when turning the vehicle on, signaling a possible fault.
  • Additionally, the vehicle may experience issues with other safety features, such as the seatbelt pretensioners not functioning correctly.

Possible Causes

Most common causes of B002A (ordered by frequency):

  1. The most common cause is a faulty airbag crash sensor, which occurs in about 60% of cases. This can happen due to wear and tear or impact damage.
  2. Another potential cause is damaged wiring or connectors in the airbag system, often resulting from corrosion or physical damage, accounting for approximately 25% of incidents.
  3. Improper installation of aftermarket accessories may interfere with the airbag system, which is a less common cause but still relevant.
  4. A less common but serious cause could be a malfunctioning airbag control module, which can affect multiple safety systems.
  5. Although rare, software issues in the vehicle's onboard computer can lead to erroneous airbag sensor readings, triggering the B002A code.
